DETAILED DESCRIPTION

Embodiments of the present disclosure are described herein. It is to be understood, however, that the disclosed embodiments are merely examples and other embodiments can take various and alternative forms. The figures are not necessarily to scale; some features could be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the embodiments. As those of ordinary skill in the art will understand, various features illustrated and described with reference to any one of the figures can be combined with features illustrated in one or more other figures to produce embodiments that are not explicitly illustrated or described. The combinations of features illustrated provide representative embodiments for typical applications. Various combinations and modifications of the features consistent with the teachings of this disclosure, however, could be desired for particular applications.

Gated entry situations typically involve strictly controlled entrances for pedestrians, bicycles, and automobiles, and are often characterized by a closed perimeter of walls and fences. Some examples of gated entry situations are gated parking lots, gated communities, police stations, and state parks. Gated entry situations may leverage V2I technology to seamlessly allow vehicles with proper authorization or access rights to enter while preventing unauthorized vehicles from entering.

FIG. 1 illustrates an example gated entry system 100. As shown, the system 100 includes a vehicle 102 attempting to enter through a gate 104, where the vehicle 102 is within proximity to an authorization device 106. In the gated entry system 100, a user at close range may handle communication between the vehicle 102 and the infrastructure (e.g., the gate 104) via the authorization device 106. In one example, the user may pull the vehicle 102 up to the gate 104, and use the authorization device 106 to make a payment, get a parking ticket, press a button, or provide identification or information that gives the user access to the gated area.

Gaining access to an area beyond the gate 104 may be based on one of two categories of system: prior authorization systems, and no prior authorization systems. In the prior authorization category, a user of the vehicle 102 may be provided with prior authorization to access the area bounded by the gate 104, but the user has to pull the vehicle 102 to the gate 104 to present identification. In the no prior authorization category, the user gains authorization to access the area protected by the gate 104 by making a payment or collecting a card to make a payment later (an example is a parking structure where the user collects a ticket upon entry and presents the same ticket while exiting to pay).

With an approach such as shown in FIG. 1, the mechanism for gaining access and entry inherently confirms that the authorized vehicle is the one at the gate 104. For example, a user pulling a vehicle 102 into a parking garage positions the vehicle 102 at the gate and presses a button, presents identification, or makes a payment. This ensures that the user is taking action to let the vehicle 102 in, and there is no free space between the authorized vehicle 102 and the physical gate 104 that could allow another vehicle 102 to enter. Since the user has to take action, this will also ensure that the user will only take action when it is his or her turn at the gate 104.

FIG. 2 illustrates an alternate example gated entry system 200 using a wireless roadside unit (RSU) 202. As shown, a first vehicle 102A is at the gate 104, while a second vehicle 102B is queued behind the first vehicle 102A. The system 200 also includes the RSU 202, which may be used to allow the vehicles 102A and 102B (collectively 102) to wirelessly communicate with the gate 104. The RSU 202 may be equipped with V2X communication functionality (e.g., DSRC, C-V2X, etc.), and the vehicle 102B may include an onboard unit (OBU) 204 also equipped with V2X communication functionality. In an example, the RSU 202 may be referred to as an V2I authorization device. These devices may be configured to automatically communicate authorization information with one another, avoiding unnecessary user interaction. Various proposed V2X gated entry systems describe authentication or payment linked to the vehicle 102, where when the vehicle 102 approaches a gate, an exchange of information occurs at very high speed without involving the user and the gate 104 opens automatically.

As shown in the system 200, the RSU 202 may have a longer range than the authorization device 106. This allows the RSU 202 to cover a broader area. When a vehicle 102 approaches the gate 104, the vehicle 120 may perform communication with the RSU 202 from a longer range and have the infrastructure ready to open the gate 104 when the vehicle 102 reaches close proximity (e.g., based on exchanged GPS information) so the vehicle 102 does not have to stop at the gate 104 at all. However, the infrastructure may be unable to verify that the vehicle 102 at the gate 104 is actually the vehicle 102 that authorized the entry. For instance, to use the example of the system 200, the vehicle 102B may authorize entry, but the vehicle 102A may reach the gate 104 first. This may be possible to occur if the vehicle 102A is not equipped with V2X technology, and therefore has not communicated at all with the RSU 202. The unauthorized vehicle 102 could then see the gate 104 opening and proceed through the gate 104 without having the proper authorization.

A similar scenario occurs when the vehicle 102 attempts to enter an area with multiple gates 104 that could lead to the same or different sections inside the gated area. In one example, an airport parking lot may include multiple gates 104 to allow more vehicles 102 to enter. Those gates 104 could also lead to different sections of the parking, such as short-term vs long-term parking. In some examples, the set of gates 104 may be operated by a single RSU 202 communicating with multiple vehicles 102. If a specific vehicle 102 requests access to a specific gate 104 at a specific lane, this information should be reliably communicated to the RSU 202 (i) to ensure the proper gate 104 is opened to this vehicle 102, and (ii) to record what gate 104 the vehicle 102 gained entry through as this might incur a different parking fee.

Moreover, inside a structure with low global navigation satellite system (GNSS) reception or no GNSS reception, GNSS may not be reliable for localizing the vehicle 102. Moreover, even with GNSS, identifying the location of the vehicle 102 will not be enough, as the RSU 202 may further have a stored map for the location to be able to localize the vehicle 102 correctly within this map.

FIG. 3 illustrates an example process 300 for the system 200, defining a process of authorizing vehicles 102 with verification. As described in further detail, the process 300 allows the RSU 202 to open the gate 104 to the appropriate vehicle 102 at the appropriate time. The process 300 may utilize one or more of various methods of verification, as described in detail herein.

At operation 302, the RSU 202 and the OBU 204 of the vehicle 102 exchange information. In an example, this could be initiated by the OBU 204 based on the vehicle 102 entering a predefined geofence or responsive to a user action. Or, the exchange may be initiated by the RSU 202, as the RSU 202 may be broadcasting its location and its capabilities and functionality. This broadcasting may be done, for example, to let vehicles 102 know that a parking structure is open and in service with a specific number of empty parking spots, that the RSU 202 is equipped with V2X technology, and that the RSU 202 is able to handle transactions over V2X.

The OBU 204 requests access rights at 304. For example, responsive to the OBU 204 and the RSU 202 establishing communication, the OBU 204 may show interest in accessing the area behind the gate 104. The request may be initiated automatically (e.g., based on GNSS location and the vehicle 102 driving toward the gate), or the request may be initiated by a prior user preference or by driver indication through the human-machine interface (HMI) of the vehicle 102.

At operation 306, the RSU 202 determines whether the OBU 204 has authorization to enter. In an example, the authorization may be determined by identifying access rights for the vehicle 102 based on exchanged data, such as an identifier of the vehicle 102 that is authorized to enter, or an identifier of a vehicle occupant who is authorized to enter. If the vehicle 102 is authorized to enter, control passes to operation 310. If not, then control passes to operation 308.

The RSU 202 determines, at 308, whether payment is collected from the vehicle 102. In an example, to gain authorization, the OBU 204 of the vehicle 102 may exchange information related to securing payment with the RSU 202. This information may include, as some examples, an account number, a user name, a signature, and/or a user biometric. If the vehicle 102 is authorized to enter, control passes to operation 312. If not, then control passes to operation 310.

At 310, the RSU 202 denies the vehicle 102 access. In an example, the RSU 202 may communicate a request denied message to the vehicle 102. The denial may, accordingly, inform the vehicle 102 and/or user that permission is denied and the vehicle 102 is unable to proceed through the gate 104. After operation 310, the process 300 ends.

At operation 312, the RSU 202 and OBU 204 perform vehicle localization and verification. In general, this operation allows the RSU 202 and gate 104 to allocate the vehicle 102 by determining exactly which gate 104 the vehicle 102 is approaching or in which lane the vehicle 102 is located. Also the RSU 202 and gate 104 may confirm that the path is clear between the vehicle 102 and the gate 104 and that the vehicle 102 can proceed through the gate 104 without obstruction. There are multiple methods that could be used separately or combined to go through these operations. Aspects of these methods of vehicle localization and verification are described in detail with respect to FIGS. 4-8.

At 314, the RSU 202 grants access to the vehicle 102. In an example, the RSU 202 may communicate an acknowledgment to the vehicle 102. The acknowledgement may, accordingly, inform the vehicle 102 and/or user that permission is granted and the vehicle 102 should be able to proceed through the gate 104. At operation 316, the RSU 202 opens the gate 104. At operation 318, the gate 104 closes responsive to the vehicle 102 proceeding through the gate 104. After operation 318, the process 300 ends.

FIG. 4 illustrates an example dataflow 400 for vehicle 102 localization and verification utilizing user input. In an example, the approach may request action from the driver. This approach may be used separately, or as a backup option for any of the other methods for vehicle 102 localization and verification discussed herein.

As shown, the RSU 202 broadcasts information regarding the gate 104. The information regarding the gate 104 may include a name of the gate 104, a location of the gate 104, and/or other information that may be used to identify the gate 104. The vehicle 102 receives this information via the OBU 204 of the vehicle 102 and displays a notification to the user of the vehicle 102 of the proximity to the gate 104 via a vehicle HMI 402. In an example, the vehicle HMI 402 includes a screen of the vehicle 102. In another example, the vehicle HMI 402 additionally or alternately includes audio prompting of the proximity to the gate 104. The HMI 402 may additionally display a list or other representation of available gates 104 or entry points to the gated area. The vehicle HMI 402 may receive a selection of a gate 104 to be entered by the vehicle 102 or in other examples with a single gate 104, an indication that the vehicle 102 intends to enter. The vehicle HMI 402 forwards this selection input to the vehicle 102, and the OBU 204 of the vehicle 102 informs the RSU 202. Moreover, the user may wait until it is his or her turn to go through the gate 104 and may request via the vehicle HMI 402 for the gate 104 to open, e.g., by pressing a button of the vehicle HMI 402 or speaking a command or taking another a similar action. The RSU 202 may, accordingly, confirm the selection.

FIG. 5 illustrates an example dataflow 500 for vehicle 102 localization and verification utilizing light encoding. As shown, the RSU 202 may share a temporary one-time code with the OBU 204 of the vehicle 102. The OBU 204 may receive this code and is configured to encode this code via LED encoding through the vehicle headlights 502. In addition, the RSU 202 may be connected to a LED light decoder in proximity to the gate 104. The gate light sensor 504 may detect the LED encoding emitted by the vehicle headlights 502 and forward the code back to the RSU 202. The RSU 202 may read the encoded code and confirm that the vehicle 102 receiving the code is present. This allows the RSU 202 to confirm that there is no obstruction between the vehicle 102 and the gate 104 and the authorized vehicle 102 is coming toward the proper gate 104.

FIG. 6 illustrates an example dataflow 600 for vehicle 102 localization and verification utilizing a gate reflector 604. As shown, the RSU 202 may request the OBU 204 of the vehicle 102 to send a basic light strobe. The OBU 204 may be configured to forward this request to the headlights 602 (e.g., through the LED headlights) of the vehicle 102. The gate 104 may be equipped with the gate reflector 604, which may be, in one example, reflective tape with an encoding to identify the gate 104 number. This encoding may be, for example, a pattern of reflective and unreflective portions that is unique for each different gate 104. The vehicle 102 headlights 602 may be equipped with a light sensor that reads the reflected code. The OBU 204 may communicate this reflected code back to the RSU 202. The RSU 202 may utilize the received information to confirm the gate 104 that the vehicle 102 is facing, is without obstruction. For instance, if the entire code sent to the OBU 204 is received back, then the RSU 202 may confirm the proximity of the vehicle 102 to the gate 104. As a variation of this approach, a camera of the vehicle 102 may be used to read the reflective tape encoding.

FIG. 7 illustrates an example dataflow 700 for vehicle 102 localization and verification utilizing radar. As shown, the RSU 202 may request the OBU 204 of the vehicle 102 to send a radar signal toward the gate 104. The vehicle 102 may be equipped with radar 702 (e.g., for use in obstacle detection, driver assistance, or autonomous driving functionality), and may use the radar 702 to send a signal in the direction of the gate 104. The radar 702 may receive a reflected signal back from the gate 104 and may verify whether there is an obstruction between the vehicle 102 and the gate 104. The OBU 204 may receive the radar echo profile from the radar 702 and may send the reflection profile to the RSU 202. The RSU 202 may receive the profile and may compare the echo profile with known good profiles to ensure there is no obstruction between the vehicle 102 and the gate 104. Moreover, the RSU 202 may be able to use the radar echo profile to identify the gate 104 the vehicle 102 is facing, as different gates 104 may be designed to have different echo profiles.

FIG. 8 illustrates an example dataflow 800 for vehicle 102 localization and verification utilizing encoded lanes 804. In this example, the vehicle 102 may be equipped with vehicle cameras 802, such as side-view cameras, for lane-keeping assistance feature. The RSU 202 may request information from these cameras 802 via the OBU 204. The request may be forwarded from the OBU 204 to the vehicle cameras 80, which may take pictures of the roadway, which may include encoded lanes 804. The encoded lanes 804 may be embedded code in lane markers on one or both sides of the pathway being traversed by the vehicle 102 to the gate 104. These codes may be unique to the different gates 104, to allow the gates 104 to be differentiated. Images of these markers may be decoded to ensure that there are no obstructions between the vehicle 102 and the gate 104. In some examples, this decoding may be performed by the vehicle cameras 802, while in other examples this decoding may be performed by the OBU 204 or other computing components of the vehicle 102. The OBU 204 of the vehicle 102 may communicate the decoded code back to the RSU 202. Using the code, the RSU 202 may localize the vehicle 102 at the gate 104 also verify that there is no obstruction between the vehicle 102 and the gate 104.

Thus, using one or more of these approaches, the RSU 202 executes the transaction and opens the gate 104. Moreover, the RSU 202 may become aware of the location of the vehicle 102 with respect to the gate 104 or gates 104 and may further be able to determine that it is the correct time to open the gate 104 for the waiting vehicle 102. The transaction may be executed and the proper gate 104 may be lifted to allow the vehicle 102 to proceed.
